Trump himself has been an aggressive critic of climate change for years. A search of the invaluable Trump Twitter Archive turns up 106 tweets in which Trump mentions "global warming" and 36 in which he used the phrase "climate change."

I mined through all of those tweets as well as a number of statements Trump has made about climate change. The 20 most dismissive are below in rough chronological order -- starting in 2012 with his oldest comments.
